Just purchased a 2011 V8 XC90 with 104k miles. I was strictly a BMW guy until now.
I notice that on the highway, if I ease into the throttle enough to prompt a downshift, the revs almost seem to go ABOVE where they should be (by ~100RPM), then "slip"/slide/fall down to the actual RPM of the gear (video here: https://youtu.be/TB5nXz5Wb9E). This does not feel like a gear slip, that is, I continue advancing forward throughout, and this might be normal behavior. I am just used to (in BMWs) downshifts being shot right to the exact RPM of the next gear then continuing forward. The one at 0:28 is the best and most focused shot of whats happening.
Anyone with the V8/3.2 with the TF80, let me know if this is normal behavior or not. I replicated it 3 times in the video. If this is normal, I see it helping others who switch from other makes too.
